Hello!
I have been playing with some optimizations on the generated code for
ARM target and x86 host. The result are the following three patches
that improve the performance by 10% for Dhrystone benchmark compiled
for the ARM7TDMI target. Also the size of the output x86 code has
shrunk by up to 40% in some cases. These patches are relatively small
and self-contained, so I would like to get them to merged eventually
if others agree.
I've some ideas for further optimizations, but implementing them would
require substantial effort and the benefits are questionable.
Big thanks goes to Laurent Desnogues who actually had suggested where
the bottlenecks are.
Best regards,
Filip Navara
